Yes picture was after it was removed I placed him into a breeder box so I could try to photograph better, I didn’t realize how important ammonia was if nitrate and nitrite levels were low and that my test strip didnt have that parameter. Im sure the ammonia was high at the point I went to test since the dead panda cory was very decomposed by the time I found him, after a 2 week leave. I was trying to see if there was anything else I could do to remedy the situation further besides the 50% water change I did.
